Monoprice 6 Zone Home Audio Multizone 12-channel Amplifier with RS232 and 70V and 4-Ohm Output

This 6-Zone Home Audio Multizone 12-channel Amplifier is a 12-channel audio distribution amp that can be configured for six stereo 4-8 ohm zones, six stereo 70/100V constant voltage zones, or three high powered 8-ohm bridged zones. It supports any combination of stereo, bridged, and constant voltage zones. It delivers 30 watts per channel into 8 ohms, 50 watts per channel into 4 ohms, or 100 watts into 8 ohms in bridged mode.
Each zone can be controlled using the included IR remote control or RS-232 computer control. The RS-232 section is bidirectional, with an easy to configure command structure. It can be configured to automatically send zone status updates or respond to queries to confirm zone status and settings.
It has an Audio Bus IN, which can be manually selected using the remote control, RS-232 commands, or a voltage trigger. The voltage trigger will switch the zone to use the Audio Bus IN as long as there is voltage present on the zone Line / Bus Trigger IN. When the voltage is removed, the zone automatically switches back to the zone Line IN, making it ideal for global paging across an entire facility.
Additionally, each zone has a Mute Trigger IN, which mutes zone audio when voltage is present. Each zone also has a +12 VDC Status or Control OUT, which can be used to activate a zone specific voltage controlled device or otherwise indicate zone ON/OFF status. Audio is rounded out with a built-in -20dB audio limiter for each zone, designed to prevent incidental peaks from becoming irrevocable problems.
Finally, each zone features a Remote Bypass switch, which allows or blocks IR and RS-232 control for those zones that you want to set and not mess with again. You can select 110-120 VAC or 220-240 VAC input voltage, allowing the amp to be used anywhere there is AC voltage. It is rack mountable, with removable rack ears for shelf mounting.
